AATCC 194-2008

Objective To evaluate the degree of anti-house dust mite activity in a long-term testing environment for textiles treated at the manufacturing level for this purpose.

Test Description Test and control specimens are inoculated with the test organism and nutrients. After six weeks of incubation, sufficient time for mite colonies to flourish under optimal conditions, the dust mites are recovered from the specimens by heat extraction. Results are expressed as per cent reduction on the treated sample versus the untreated control.

Customer Benefit The data generated by this test provides a good measurement of the effectiveness of anti-dust mite treatment on a breeding mite colony. However, this test method cannot be used to predict the performance of a fully constructed product if the test specimen represents only a component of the final article. It also is restricted to textiles only and cannot be used to assess the corresponding effect on the removal of allergen, which will remain even after the removal of house dust mites.

Third Party Validation On passing this test, the fabric can be labelled as having been tested by airmid in support of any claim relating to the test and data received
